Answer:
You can increase the kinetic thermal water by many physical changes like boiling and even when it evaporates
Explanation:
that statement is true
a Third class lever applied when the effort place between the load and the fulcrum.
For example, in a forearm serve
Fulcrum : The elbow
Effort : The effort that putted by the biceps muscle
Load : The arm
Total amount of energy would remain constant according to law of conservation of energy. i.e., 50 Joules
In short, Your Answer would be Option C) <span>50 Joules because as energy converts from one form to another, it cannot be created or destroyed during the conversion.

Hope this helps!
Explanation:
The attached figure shows data for the cart speed, distance and time.
For low fan speed,
Distance, d = 500 cm
Time, t = 7.4 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{7.4}\\\\v=67.56\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B7.4%7D%5C%5C%5C%5Cv%3D67.56%5C%20cm%2Fs)
Acceleration,
![a=\dfrac{v}{t}\\\\a=\dfrac{67.56}{7.4}\\\\a=9.12\ cm/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B67.56%7D%7B7.4%7D%5C%5C%5C%5Ca%3D9.12%5C%20cm%2Fs%5E2)
For medium fan speed,
Distance, d = 500 cm
Time, t = 6.4 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{6.4}\\\\v=78.12\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B6.4%7D%5C%5C%5C%5Cv%3D78.12%5C%20cm%2Fs)
Acceleration,
![a=\dfrac{v}{t}\\\\a=\dfrac{78.12}{6.4}\\\\a=12.2\ cm/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B78.12%7D%7B6.4%7D%5C%5C%5C%5Ca%3D12.2%5C%20cm%2Fs%5E2)
For high fan speed,
Distance, d = 500 cm
Time, t = 5.6 s
Average velocity,
![v=\dfrac{d}{t}\\\\v=\dfrac{500}{5.6}\\\\v=89.28\ cm/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B500%7D%7B5.6%7D%5C%5C%5C%5Cv%3D89.28%5C%20cm%2Fs)
Acceleration,
![a=\dfrac{v}{t}\\\\a=\dfrac{89.28}{5.6}\\\\a=15.94\ cm/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv%7D%7Bt%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B89.28%7D%7B5.6%7D%5C%5C%5C%5Ca%3D15.94%5C%20cm%2Fs%5E2)
Hence, this is the required solution.
